The Dart Compiler (as a Ruby Gem)

The dart-compiler gem is a svelte wrapper around the Dart Compiler (Dart to JavaScript compiler)

The Dart Compiler’s 2011-10-12 JAR-files are included with the gem.

Installation

sudo gem install dart-compiler

Usage

require 'rubygems'
require 'dart-compiler'
Dart::Compiler.new.compile(File.open('hello.dart', 'r'))

=> "function native_ArrayFactory__new(typeToken, length) {......

When creating a Dart::Compiler, you can pass any options that the command-line compiler accepts to the initializer and they’ll be forwarded.

A Dart::Error exception will be raised, explaining the Dart syntax error, if compilation fails for any reason.
